WiFi Calling Doesn't Work at Home

[jerryfudd]

Hi,

I get pretty poor signal at home and used to have a SureSignal box which stopped working but found out I can use Wifi Calling, this is now enabled and works at my workplace however not at home.

Do specific ports need to be opened up on my home router in order to allow certain traffic by to my device? (S9 and S10+).

Hi @jerryfudd 

WiFi calling will kick in when there is zero mobile signal, it may be there is limited signal at your home address but adequate for calling.

Try putting your phone on offline mode with WiFi turned on, you may find it will WiFi calling will work.

Hi, 

Thanks for your reply, I put the phone into airplane mode and then turned on the WiFi making sure WiFi calling was on but still didn't activate.

It was working fine before I left work though. I've tried restarting the router and all the simple things but wondered if the required ports might be being blocked and needed to be manually opened.

I have EXACTLY the same problem! Please could someone help resolve this.

My wifi calling works at the office (even though there is full reception there), however it does not work at home. I have tried all of the standard suggestions - rebooting my phone, switching airplane mode on, switching WiFi calling on and off etc. I think it is more a problem with my home WiFi which is also provided by Vodafone. Do I need to do something with the router?

I am using a Samsung S10 device.

It is super frustrating because my reception at home is minimal and means that making calls is practically impossible.

Thanks in advance!

I had to enable 'SIP' on the router's firewall - and of course on the phone.

If you have a BT router its under Advanced Settings > Firewall

Not sure if you resolved this but on my router I had to enable IPSec pass-through in the NAT Forwarding section of my router then wifi calling works perfecly. (Router is a TP-Link device)
